Which of the following are reasons for deforestation?

• paper, mining, logging, agriculture

• wood, building supplies, fossil fuels, coal

• destroying habitats, disrupting carbon cycle, blocking sunlight

Tags

NGSS.MS-ESS3-4

Why deforestation a problem?

• Destroys habitats/disrupts carbon cycle

• Creates an overabundance of carbon dioxide, makes room for cities

• increases greenhouse gas, rising sea levels

• depletes ozone, burning fossil fuels, factories emitting greenhouse gas
