The reason for this sudden global call to save earth is the destructionthat has changed the face of earth. Problems like global warming,pollution, overuse of minerals, deforestation and natural calamitieslike volcanic eruptions, tsunamis, earthquakes, etc. have causeddestruction on earth.
is there a need to save
• Organic pollution
• Agricultural pollution
• Runoff, toxic waste
• Thermal pollution.
EUTROPHICATION.. Undue
enrichment of a lake, river etc. with nutrients, resulting in growth of organisms and depletion of oxygen level in water.
More is water pollution more is the pressure on the environment.
Waste that come from the sewage plant encourage the growth of algae.
Overgrowth of algae water soon becomes algae ridden and oxygen become depleted.

What are the Causes of Deforestation?The destruction of the forests is occurring due to various reasons, one of the main reasons being the short term economic benefits.Given below are some more common causes of deforestation:Used for Urban and Construction Purposes: The cutting down of trees
for lumber that is used for building materials, furniture, and paperproducts. Forests are also cleared in order to accommodate expandingurban areas.
To Grow Crops: Forests are also cut down in order to clear land for growing crops.To Create Grazing Land: Forests are cut down in order create land for grazing cattle.Used for Fuel: Trees are cut down in developing countries to be used as firewood or turned into charcoal, which are used for cooking and heating purposes

Solar energy
Warming of the Earth’s core
CO2 levels increasing because warmer oceans release more CO2
In turn global warming could lead to global cooling
Energy in our Lives:Energy is essential. We use it for heat, electricity, transportation and manufacturing. We all need it to stay warm, to cook food and to have light in the night. We use energy to fuel our airplanes and cars and we use it to make things in factories. Everything from peanut butter to plastic bottles, from T-shirts to cell phones takes a lot of energy to make.
Where does the worlds, energy come from today? Over 85% of it comes from fossil fuels like coal, oil and natural gas. The rest comes from many other sources like wind, water, radioactive atoms and the sun.
Are Humans Causing the Climate to Change?
98% of greenhouse gas emissions are natural
2% are from man-made sources
Warmed slightly in the last 100 years, 70% of warming occurred prior to 1940
