Science Unit 5 Lesson 5

Question 1

Main goals of sustainable farming?

Answer 1

The goal of sustainable farming practices is to meet a community’s current needs for food and commodities while protecting resources for future use. Sustainable farming practices are tailored to the specific needs of a region based on geography, climate, and the crops being cultivated. Farmers need to consider carefully the short- and long-term costs and benefits of each conventional and sustainable farming option.

Question 2

What is intercropping?

Answer 2

The sustainable practice of intercropping involves growing multiple crops on the same plot of land. It is the growing multiple crops on the same plot of land. It also increases soil quailty.

Question 3

How can agroforestry and alley cropping affect the atmosphere?

Answer 3

When farmers plant trees for alley cropping—or even maintain existing forests in more complex forms of agroforestry—they allow for greater carbon storage. When more carbon dioxide is stored, less carbon dioxide is in the atmosphere, which slows down the process of climate change.

Question 4

What is the definition of carbon sequestration?

Answer 4

the process by which carbon dioxide is removed from the atmosphere and stored

Question 5

Why are palm oil plantations bad for the environment?

Answer 5

oil palm plantations are often referred to as “green deserts” due to their lack of biodiversity. Clearing existing rain forest to make room for monoculture oil palm plantations has had a significant environmental impact in Indonesia and Malaysia, which produce over 80 percent of the world’s palm oil.

Question 6

Which places face the most environmental impact due to palm oil?

Answer 6

Indonesia and Malaysia, which produce over 80 percent of the world’s palm oil.
