True or False
True
What is logging?
Companies cut down trees for profit and turn them into products for human consumption.
What is clear-cutting?
Why is it the most common method of harvesting trees?
Clear-cutting is when all the trees in one area are cut down, no matter their size or age. It’s the cheapest and fastest way to cut down trees.
What is selective cutting?
What makes this the un-preferred method?
Selective cutting is when only certain trees are cut down, based on things like their age or health. It’s more expensive and takes more time than clear-cutting.
While we do replant trees, do we change the look of the forest?
How is this a problem?
Yes, because we often plant just a few types of fast-growing trees, which reduces the variety of tree species. Fewer types of trees means the forest is less healthy and less diverse, which harms wildlife.
How does urban growth threaten forests?
As cities grow, forests are cleared to make space for buildings and roads, which destroys habitats.
What is habitat fragmentation?
Habitat fragmentation happens when forests are broken into smaller pieces, making it hard for animals to move around.
How does agriculture threaten forests?
Farmers clear forests to grow crops or make space for animals. They use methods like slash and burn, where they chop down and burn trees to clear land.
How do invasive species threaten forests?
Invasive species like certain bugs can kill trees or spread diseases, hurting the forest.
How do forest fires threaten forests?
Forest fires can destroy trees, harm wildlife, and release pollution into the air.
How can you help our forests?
Planting a tree to help absorb carbon dioxide and give oxygen.
Joining a group that supports forest protection.
Voting for leaders who care about the environment.
Buying products from companies with the FSC label, which means they are responsible about trees.
Practicing the 3 R’s:
Reduce paper use, like going paperless and reusing both sides of paper.
Reuse products instead of using disposable ones.
Recycle paper and buy recycled paper products.
