Thise problem seruiously influences on both nature and hunmans?

Effect on nature and human Rise in sea level worldwideClimate change Massive crop failures

Effect on animals and sea lifeImpact on creatures and human

beings Widespread extinction of speciesDanger for ocean ecosystems

Solutions of global warming issue Reduce greenhouse Use alternative energy supply sources,

like wind and solar power..cte…. Use less transportation based on fuel Short distances should be done by foot or

bicycle Stop deforestation Increase forestlands and plant more trees Use of biofuel

Humans: -use less chemical fertilizers - use more bio-fertilizers rather than chemical substances -reduce industry emissions-use less consumer products

In conclusion , global warming is the biggest and serious issue faced by us. The countries around the world, particularly the world powers have concerned about this problem, and take measure in order to clam that the industrialized countries should reduce their emissions as much as possible . It a good conduct to preserve nice earth for the generations sustainably.
