EARTH  DAY
1. Pollution: Because Due to human impact make the earth we live was serious air pollution and water pollution and soil.
2. Overpopulation: because The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food. Population explosion in less developed and developing countries is straining the already scarce resources.Overpopulation is one of the crucial current environmental problem.
3.  Loss of Biodiversity: because  Human activity is leading to the extinction of species and habitats and and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating.
 I think the celebration of Earth Day is important because we live on this earth to make the festival we want to live in this planet is what it does what it is protected in the day, it is important to celebrate Earth Day.
