biodiversity and waste management

• biodiversity is the variety of different species of organisms on earth , or within an ecosystem
• high biodiversity means ecosystems are stable because species depend on each other for shelter and food etc. also help maintain the right physical environment
• human activity is reducing biodiversity
• population is currently rising. This is due to modern medicine and farming methods. Big effect of environment we live in
• our increasing population puts pressure on the environment as we are taking resources needed to survive
• people demand a higher standard of living. use more raw materials and energy for manufacturing process. taking more resources from the environment quickly
• many raw materials are used up quicker than being replaced; we are running out
• making more things produce waste
• pollution caused from waste affects water, land and air and kills plants and animals, reducing biodiversity
• sewage and toxic chemicals pollute water, affecting the plants and animals that rely on them. chemicals used on land can be washed into them.
• we use toxic chemicals for farming and bury nuclear waste underground and household waste into landfill sites
• smoke and acidic gases released into the atmosphere can pollute the air, sulfur dioxide can cause acid rain.
• we avoid moisture, sunlight and microbes around landfills to avoid decomposition and release toxic chemicals
