Too much “greenhouse effect” can cause global warming.

Global Warming Global warming can drastically change the environment.

The Ozone Layer

Too much carbon emission can also destroy the Ozone Layer. The Ozone Layer helps protect us from the sun’s UV Rays. The Ozone Layer

What causes global warming?

Trees give oxygen (O2) to the environment. Deforestation destroys forests by burning and cutting down trees. Deforestation

Smog is the result of too much carbon emissions being released. Many factories release “smoke” into the air, which creates smog. Smog

Energy over consumption is the use of too much electricity. Too much electric use strains many power plants. Power plants also release carbon into the environment. Energy Over Consumption

Garbage disposal is the act of destroying garbage. Destroying too much garbage consumes a lot of energy. Garbage Disposal

Too many vehicles builds up carbon emissions. “Smoke” from the vehicles also creates smog. Traffic

In Texas and California, large cow farms produce a lot of methane. Methane can also destroy the O- zone. Methane
