The whole world has a real problem: Unlike other materials, plastic does not biodegrade.Almost all plastics are made from chemicals that come from the production of planet-warming fuels (gas, oil and even coal). So Plastic also contributes to global warming.
How can we conserve the ecosystem?
A good way of conserving the ecosystem is reducing, reusing and recycling. If we don’t recycle, lots of plastics will arrive in ecosystems and damage them.
Ecosystem conservation provides us with clean air, water, and food, supports biodiversity, mitigates the impacts of climate change, and promotes sustainable
development.
