Biodiversity is the variation of Earth’s terrestrial, freshwater, and marine species, as well as their habitats. Biodiversity is vital to the survival of all life on earth and is also the cornerstone for the goods and services of the environment that allow human societies to thrive. Biodiversity provides us with food, water and resources as well as services such as climate control, pollination, flood mitigation and cycling of nutrients

2. ENVIRONMENT’S
World Environment Day is the most renowned day for
environmental action. Since 1974, it has been celebrated every year
on 5 June; engaging governments, businesses, celebrities and citizens
to focus their efforts on a pressing environmental issue
THEME OF 2020
In 2020, the theme is biodiversity–a concern that is both urgent and
existential. Recent events, from bushfires in Brazil, the United States
and Australia to locust infestations across East Africa–and now, a
global disease pandemic–demonstrate the interdependence of humans
and the webs of life in which the yexist. Nature is sending us a
message.

3. THE COMMUNITY
Above all, World Environment Day offers a global platform for inspiring
positive change. It recognizes that global change requires a global
community. It pushes for individuals to think about the way they consume;
for businesses to develop greener models; for farmers and manufacturers to
produce more sustainably; for governments to safeguard wild spaces; for
educators to inspire students to live in harmony fierce gatekeepers of a green
future. It requires all of us. with the Earth; and for youth to become
HISTORY
World Environment Day [WED] was established by the UN General assembly
in 1972 on the first day of the Stockholm Conference in the Human
Environment, resulting from discussions on the integration of human
interactions and the environment. Two years later, in 1974 the first WED was
held with the theme "Only One Earth". Even though WED celebration have
been held annually since 1974, in 1987 the idea for rotating the center of these
activities through selecting different host countries began.

Biodiversity is the variation of Earth’s terrestrial, freshwater, and marine
species, as well as their habitats. Biodiversity is vital to the survival of all
life on earth and is also the cornerstone for the goods and services of the
environment that allow human societies to thrive. Biodiversity provides us

pollination, flood mitigation and cycling of nutrients
Ecosystems are relying on all parts from the smallest bacteria to the largest
vertebrate. It’s all interconnected. Some are producing oxygen that others are
breathing. Some provide food for larger species, which in turn become prey to
even larger species. Every living organism has a role to play in the
maintenance of balance.
You can ultimately lose much more than one species by removing one
element. More than 98% of the species in nature are extinct.

6. Major factors that affect our Environment
 Air Pollution
 Overpopulation
 Deforestation
 Climate Change
 Global warming

7. AIR POLLUTION
Air pollution refers to the release of pollutants into the air that are
detrimental to human health and the planet as a whole
CAUSES OF AIR POLLUTION
SMOKE AND SOOT
HAZARDOUS AIR POLLUTANTS
GREEN HOUSE GASES
POLLEN AND MOLD

8. OVER POPULATION
As with every environmental problem, while there are many solutions to
pollution, adding more people to the population adds more polluters and
makes those solutions less effective. While rich countries produce
more plastic waste per person, for instance, poor regions where population
growth outstrips the infrastructure to dispose of waste may contribute
more plastic overall.

10. DEFORESTAION
The deforestation causes include
many factors. The destruction of
the forests is occurring due to
various reasons, one of the main
reasons being the short-term
economic benefits. Corruption at
the government institutions,
wealth and power due to
harvesting of the riches of the
forest, population growth and
urbanization are some of the
common causes.

12. CLIMATE CHANGE
Climate change, also called global warming, refers to the
rise in average surface temperatures on Earth. An
overwhelming scientific consensus maintains that climate
change is due primarily to the human use of fossil fuels,
which releases carbon dioxide and other greenhouse gases
into the air. The gases trap heat within the atmosphere,
which can have a range of effects on ecosystems, including
rising sea levels, severe weather events, and droughts that
render landscapes more susceptible to wildfires
