Some steps society can take to help reduce the effects of acid rain include:
- Implementing regulations to limit sulfur dioxide and nitrogen oxide emissions from power plants and other industrial sources. Many areas have seen reductions in acid rain as a result of these emissions regulations.
- Transitioning from fossil fuels like coal to cleaner energy sources such as natural gas, solar, wind, nuclear and hydropower which produce fewer acid rain causing emissions.
- Developing and adopting technologies that can capture sulfur dioxide and nitrogen oxide emissions from large stationary sources before they are released into the air.
- Educating the public about acid rain causes and effects so individuals can make choices that produce fewer emissions, such as driving less, improving energy efficiency

ost of us live our lives seemingly apart from nature. We make
our homes in cities and towns, surround ourselves with con-

The closest many of us get to nature is a romp with the family dog
on the grass in the backyard. A lucky few come in much closer con-
tact with the great outdoors through hiking, camping, canoeing, and
kayaking. For many of these people, though, nature is still viewed
as something apart from humans—a thing to protect to preserve a few

CRITICAL THINKING
Exercise
The information gained from various fields of
science such as ecology is often loosely trans-
lated in the public arena. Terms are some-
times misinterpreted. Facts are taken out of
context. New findings are given more cre-
dence than they deserve, and old, disproved
ideas remain in the popular thinking for a
long time. As you read this chapter, make a
list of terms, ideas, concepts, and facts you
encounter that contradict what you thought
was true.
pendence first by taking a look around the room in which you
are sitting. Everything in that room comes from the Earth or
a natural system. The clothes you wear, your morning tea or
coffee, and even the cornflakes you ate for breakfast are
products of the Earth—the soil, water, air, and plants.
Like all other species, humans depend on the soil, air,
water, sun, and a host of living organisms to survive. Each
year, in fact, human beings (and other animals) consume
enormous quantities of oxygen, which is used in the cells of
our bodies to break down food molecules to generate en-
ergy. Oxygen is produced by plants and algae. Without these
organisms, humans and other animals could not survive.
Trees, grasses, and other plants also provide a host of addi-
tional free services. For example, plants protect the water-
sheds near our homes, preventing flooding and erosion.
Swamps purify the water in streams and lakes—water many
of us drink. Birds help to control insect populations.
Clearly, nature serves us well. Although many of us have
isolated ourselves from nature, we still depend on nature in
many ways. We have not emancipated ...

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
