Ocean debris, also known as marine debris or marine litter, is human-made waste that ends up in bodies of water. While some natural debris like driftwood has occurred for thousands of years, plastic pollution has severely increased as plastic does not biodegrade. Animals often mistake debris for food which can cause injury or death when it blocks their digestive systems. Toxic chemicals from plastic can also leak into waters. Various methods are used to remove debris from beaches and coastlines, but much remains floating in oceans. Common debris items include plastic bags, bottles, balloons, fishing nets, and other materials from ships. Studies show 80% of debris is plastic, which is especially harmful as it never decomposes and can kill over one

Polar bears rely on sea ice to hunt seals. As Arctic temperatures rise, sea ice declines and melts earlier each year. This reduces polar bears' time to hunt, causing them to lose weight and reproductive ability. Some polar bear populations have declined by 20% already. If warming continues, scientists project 2/3 of polar bears could be gone by 2050. The melting Arctic sea ice also threatens polar bears' habitat and forces interactions with grizzly bears invading from the south.
Trains are more energy efficient and produce less greenhouse gases than buses according to three key metrics. Trains emit fewer kilograms of carbon per kilometer traveled and require less megajoules of energy than buses. While trains are better for the environment, buses can drop passengers closer to their final destination within a suburb, while trains only travel to the suburb and require connecting bus service for the last leg of the journey. However, trains are quicker and cheaper than bus-train combinations.
The black rhinoceros is an endangered species native to parts of Africa. Their population has declined dramatically due to poaching for their horns, which are used in Chinese medicine and for carvings. Black rhinos now number only around 2,300 total. They are solitary animals that eat woody plants and drink water at dusk and dawn. While they have no natural predators, they are vulnerable to poachers who ambush them at water holes. Conservation efforts are working to protect the remaining black rhino populations from extinction.
The document discusses sustainable public transport options and their environmental benefits over traditional cars. It examines different modes of public transport like buses, trains, and proposed innovations like maglev trains, monocabs, and straddling buses. These options emit far less greenhouse gases than cars and could help address issues of climate change, air quality, and depleting energy resources if more people adopt public transport. The document also outlines the author's research findings on sustainable transportation topics.
Tigers are endangered due to threats like deforestation, hunting, and poaching. There are only around 3,900 tigers remaining in the wild. Tigers can be found in Asia and come in different subspecies depending on their region. They are carnivores that prey on animals like deer. Deforestation is a major threat as it destroys tiger habitats and reduces their food sources. Traditional medicine practices have also increased poaching of tigers for their body parts. Increased human activity is the biggest threat to tigers' long term survival.
Deforestation threatens mountain gorillas in three key ways: 1) It reduces their habitat as forests are cleared for agriculture, mining, and logging. 2) It brings humans into closer contact with gorillas, increasing the risk of disease transmission. 3) It makes gorillas more accessible to poachers by removing forest cover that previously protected gorillas. Deforestation is the underlying driver that exacerbates threats from disease and poaching to these endangered great apes.

This document discusses various topics related to recycling in Australia. It provides information on:
1. Common items that can be recycled such as paper, cardboard, plastics, glass, metals, e-waste, batteries, and food scraps.
2. Benefits of recycling including reducing waste sent to landfills, conserving natural resources, saving energy, and reducing pollution.
3. Proper procedures for recycling different materials through municipal collection programs or special drop-off locations.
The document discusses ways to make a house more sustainable, including proper orientation, insulation, efficient appliances, renewable energy sources, water and energy saving techniques, sustainable transportation, composting, and native landscaping. Some specific recommendations are installing solar panels, switching to LED lighting, using a geothermal heat pump for air conditioning, and driving an electric or hybrid vehicle.
The document discusses the Carnaby's Cockatoo, a bird native to Western Australia that is facing serious threats to its population and habitat. Habitat destruction from logging, urban development, and agriculture has cut the cockatoo's population in half. Conservation groups are working to help the species by restoring nesting hollows and protecting habitat from further destruction. Solutions proposed include creating nature reserves, planting native trees, and making artificial nesting hollows to try to restore the dwindling population of the Carnaby's Cockatoo.
Koalas are listed as threatened due to habitat loss, diseases like chlamydia, and climate change. Diseases are reducing koala numbers while development destroys habitat. Translocation is stressful for koalas but protects them from bulldozers. To help koalas, people can donate, plant eucalyptus trees, and raise awareness of threats like hot weather and lack of suitable habitat.
This document discusses snakes, including their habitat, behavior, predators and prey, how they help the environment, and interesting facts. It references four sources for additional information on snakes - a book on snakes and reptiles, the Wikipedia entry on snakes, a website on rat diseases, and a book on snakes published by DK Books.
Global weather patterns are changing, leading to extreme natural disasters like hurricanes and floods. Hurricane Isaac in 2012 caused $3 billion in damage and killed thousands after making landfall in America. In just one week in 1998, the US experienced a series of abnormal and damaging weather events including floods, tornadoes, earthquakes, and wildfires, showing that changes in weather trends were occurring as early as the late 1990s. The document discusses how weather patterns are shifting globally and the damage that extreme weather events can cause.
This document summarizes and compares three renewable energy sources: solar, wind, and hydro power. [1] It discusses what each energy source is, along with their advantages and disadvantages. [2] The key advantages are that solar and wind are inexhaustible resources with no pollution, while hydro is inexpensive once dams are built. [3] The main disadvantages are that solar has low energy production, wind requires windy areas and has downtime, and hydro is limited by water availability.
Cows release significant amounts of methane daily, which contributes to global warming. A single cow produces approximately 214kg of methane per year, or 58g per day. Globally, the 1.3 billion cows release around 760 million kg of methane daily. Methane is a potent greenhouse gas that is 23 times more effective at trapping heat than carbon dioxide. While the methane from cows does not directly harm nearby animals, it does impact the environment by contributing to climate change. Some methods to reduce methane from cows include changing their diets or capturing methane from cow manure.
This document discusses the issue of overfishing and its consequences. It explains that overfishing occurs when fish populations cannot replenish themselves quickly enough due to too many fish being caught. Major causes are industrial fishing trawlers that indiscriminately catch huge amounts of fish and sea life. This has depleted fish stocks by 70% and threatens the extinction of many species like bluefin tuna, sharks, and whales by 2050 if no action is taken. The document urges people to choose sustainable seafood options and petition against destructive fishing practices to help protect ocean ecosystems.
This document reports on a family's efforts to reduce their household water usage over three weeks. They implemented a plan where they set a timer for 15 minutes in the shower. While their water usage initially increased in the second week due to having more people doing laundry, by the third week with only two people at home their water usage dropped significantly. They concluded that investing in a more water efficient washing machine could help reduce their usage further.
Sahil's household implemented a water saving plan that helped them reduce their water usage by over 1000 liters for the week. Everyone in the household played a part in conserving water. The document provides additional tips to make the household even more water friendly, such as collecting rainwater, checking weather forecasts, and obeying all water saving rules. It recaps the household's water usage over three weeks, showing improved conservation from planning and teamwork. The document encourages the household to continue their efforts to be water friendly and save money.
My family monitored their weekly water usage over three weeks and found that their afternoon usage was the highest, likely due to showering and running the dishwasher. To reduce usage, they implemented an action plan of shorter showers, using eco settings on appliances, and turning taps off. Comparing the first and third weeks, their total weekly usage decreased from 1871L to 1082L, then to 835L, showing their plan was effective. They were pleased to save water and reduce the water bill.
The document details a household's weekly water usage over three weeks and the results of implementing a water conservation action plan. Week one recordings showed morning showering as the main water use. An action plan focused on reducing shower time and reusing water. Week two saw reduced usage, though a water leak repair impacted results. Minor adjustments were made. Week three saw overall usage decrease, though evening use increased slightly. The plan was effective but high weekend and shower water usage remained.
Leif Logie implemented an action plan to reduce his household water usage. In the first week, the household used an average of 2650L per day. After implementing a plan involving shorter showers, less tooth brushing water, eco washing cycles, and only washing clothes as needed, usage dropped to 1240L in week 2, a savings of 1410L. In week 3, with minor changes, usage further dropped to 1020L, a total savings of 1630L compared to week 1. The action plan proved very effective in significantly reducing the household's water consumption.
This document summarizes the water usage of a sample household over three weeks as they tried different strategies to reduce their water consumption. In the first week, their baseline usage is recorded. In the second week, they aimed to wash dishes and clothes less frequently. This helped reduce their mid-week water usage. In the third week, they attempted to shower every other day, but the plan did not work due to resistance from one family member. Overall, their experiment was considered a partial success, as they did develop a habit of using less water for clothes and dishes washing.
This document describes a student's investigation into their family's daily water usage. The student measured their morning, afternoon, and evening water consumption over 7 days to establish a baseline. They then created an action plan to reduce usage by shortening shower times, collecting shower water for the garden, running appliances less and only when full. The student measured consumption again over 14 days and found that while usage was not significantly lower due to existing conservation habits, the exercise increased family awareness of water usage. The student learned that small individual changes can lead to large savings if adopted by many.
The homeowner noticed their water meter was leaking and installed a new one to see if it would reduce water usage. Records showed over 4m3 was used on the first day of monitoring. After installing the new meter, usage dropped to 0.33m3 in a day and averaged 0.69m3 over 8 days. While the new meter interrupted data collection, the results demonstrate much higher usage with the old, leaking meter compared to after installing the new one.
This student monitored their household water usage over two weeks and found they were using more water than average, especially in the evenings. They created an action plan to reduce water usage by installing a 4 minute shower timer, using the half flush on the toilet, and an eco wash setting on the dishwasher. After implementing these changes, their weekly water usage dropped significantly from 11,200 litres to 3,280 litres, saving them around 8,000 litres per week.
1) Perth households use an average of 276 kilolitres of water per year, double that of Melbourne and Brisbane. Most of Perth's water comes from underground aquifers near the surface or deeper down.
2) The family tracked their water usage over 3 weeks and implemented an action plan to reduce usage by at least 10% by turning off taps when not in use, taking shorter showers, and using efficient settings on appliances.
3) On average, their daily usage decreased by 9%, just short of their 10% target. The student learned about varying water usage and the importance of clean water access for many people worldwide.

1. My Water Wise Project
By Anna#
Week 1
I found that we used the most water when in the evening, when Alistair had
a bath, Miriam and I had showers, and the dishwasher was turned on. We
also used a lot of water on days when the washing machine and dishwasher
were used the most.
My Water Wise Plan
My plan was to:
o Limit showers to four minutes,
o Use the dishwasher and washing machine on the eco setting only
and
o Limit Alistair’s bath to 10 centimetres of water
What My Family Thought of It
“I think it’ll work” -Mum
“The dish washer works best when it’s on the normal setting, but it’s a
pretty good plan”- Dad
“Four-minute showers? I can do that, but don’t you dare make it lower
than three”- Miriam
“Can I watch ABC kids now? Please?” –Alistair
What I Thought of It
“I think that I found the best ways for us to reduce our water use. I
think it work, as long as Dad doesn’t use the dishwasher and washing
machine on whatever setting he thinks is the best, but I may have to
reduce the shower times, or find something else to implement. Apart
from that, I’m pretty confident about it.”
Week 2
This week, I found that the average water use per day in our house went
2. down by just over 50L, to 387L, from 440L. We still used the most water in
the evenings, so I adjusted my plan to three-minute showers instead of four.
What My Family Thought of My Changes
“It’ll work better now, I think” - Mum
“You do know the dishwasher works best on the normal setting, don’t
you? It’s probably going to be more effective, though.” – Dad
“Three minute showers? I need my long showers!!!” – Miriam
“ Can you play cars with me?” -Alistair
What I Thought of My Changes
“I think we can reduce our water use even more than what we already
have. Two-minute showers would have been better, but then Miriam
would have ignored the timer, and had a longer shower anyway,
probably longer than three or four minutes. And Dad, don’t you dare
use the dishwasher on anything other than the eco setting!”
Week 3
This week was the worst week in terms of our water use. The daily average
went up to almost 500L (488L). I think this was because Mum started
training for a half-marathon with her sisters and sister-in-law, and Mimi and
I came along to their training sessions in Kings’ Park and Lake Monger early
in the morning, so we were having two showers per day instead of one. The
shower timer also broke half-way through the week when Alistair dropped it
several times. I also think that people just got bored with my plan, especially
Dad, who used the dishwasher on the normal setting most of the time.
What My Family Thought on How My Plan Worked
“It was a good plan, but it wasn’t implemented very well.” –Mum
“I had three-minute showers, but I used the dishwasher on the normal
setting because it washes better.” – Dad
“See what I mean?”-Mum
“It was pretty hard to implement. It takes three minutes for the
shower to warm up, and I got bored with short showers and had long
ones sometimes” – Miriam
“Can I watch Cars (a Disney/Pixar movie, and Alistair’s current
favourite) on the T.V?” – Alistair
