Hi there.
00:04
In this question, we want to decrease the amount of co2.
00:09
So of course, the answer to that would be to increase the number of plants.
00:20
Be that small plants, large plants, trees, we want to increase the number of plants because plants use carbon dioxide, of course, and sunlight in the process of photosynthesis.
00:31
The other thing we want to do, though, is increase the amount of biodiversity.
00:42
And biodiversity means variety.
00:54
Okay, so let's look at our options here.
00:55
Looks like we have four options.
01:01
The first one says planting more trees, they're going to absorb carbon dioxide from the atmosphere.
01:07
That one sounds pretty good, especially if we're planting a variety of different trees, and then trees provide habitat for other organisms, thereby increasing the biodiversity.
01:18
So this first statement sounds pretty good.
01:22
Let's look at the next one.
01:23
Converting forests into housing developments.
01:26
Well, that's not going to increase the amount of carbon dioxide use...
