This document discusses several global environmental issues including global warming, ozone layer depletion, acid rain, marine pollution, deforestation, biodiversity loss, desertification, and radiation contamination. It provides statistics on world population growth and increasing global demands for energy and protein. Greenhouse gases like carbon dioxide, methane, nitrous oxide, and CFCs contribute to global warming by trapping heat in the atmosphere. The document advocates for renewable energy solutions like wind and biogas from dairy farms to help address these environmental challenges and create a more sustainable future.

Sun
Some solar radiation is reflected
the earth’s surface and the atmosphere
１０３ Ｗｍ －２
Atmosphere
Most solar radiation is absorbed
by the surface and warms it
Earth
Some of the infrared radiation
Is absorbed and re-emitted by
the greenhouse gases.
The effect of this is to warm the
Surface and the troposphere
Infrared radiation is emitted
from the earth's surface

10. 
 Climate change will change our life on Earth and will
affect all nations, all plants, all animals, all humans,
all living beings on Earth.

11. 
 We use Renewable Energy
We show you how to use Renewable Energy and we
explain why. We defend our oceans by challenging
water pollution and wasteful and destructive fishing.

17. Conclution:
We work hard to protect all forests on
Earth and the animals, plants and
people that depend on them.
We work hard to create a toxin free
future with safer alternatives to
hazardous chemicals.
We campaign for sustainable
agriculture.
We want to protect biodiversity.
