7.3 Plants Convert Solar Energy -- Part 2
PS I is next to the NADP reductase, which reduces NADP+ to NADPH.
Leonardo DiCaprio strives to make global changes through his foundation, even though he is a famous actor.
Tropical rain forests are protected by the Leonardo DiCaprio Foundation.
Most people think about saving the plants and animals that live in the rain forest, but there is a bigger issue at hand.
Prior to 1850, atmospheric carbon dioxide levels remained constant at 0.028%.
When industrialization began, the amount of CO2 in the atmosphere increased to 0.04%.
The gases are called greenhouse gases.
The Earth's temperature would be 33 degrees cooler without greenhouse gases.
The concentration of greenhouse gases makes the Earth more acidic.
CO2 is added to the atmosphere by burning fossil fuels.
Tropical rain forest destruction contributes to an increase in atmospheric CO2
Tropical rain forests are considered the "lungs" of the Earth by many scientists.
Between 10 and 30 million hectares of rain forests are lost every year to ranching, logging, mining, and otherwise developing areas of the forest for human needs.
If you lose lung capacity, you lose function in your body.
Burning a forest adds CO2 to the atmosphere and removes the trees that would normally absorb it, which is a bigger problem for climate change.
The process of removing carbon dioxide from the air is called photosynthesis.
It is estimated that organic matter is several hundred times the mass of the people living on Earth.
These environments act as a sink for CO2, preventing too much from accumulating in the atmosphere, where CO2 can affect global temperatures and bring about climate change.
Tropical rain forests still make a significant contribution to global CO2 removal despite their reduced size.
They are essential for normal, healthy function and are a critical element of the Earth's systems.
Tropical rain forests are the most efficient in the world and contribute greatly to the absorption of CO2 and the productivity of photosynthesis.
Near the equator, there are tropical rain forests.
They can be found wherever the temperature is above 26degC and the rain is heavy.
There are huge trees with broad trunks and dark-green leaves.
Most of the land plants in a tropical rain forest are vines.
It is possible that an increase in the amount of CO2 in the atmosphere will increase the amount of sunlight entering the forest.
Recent studies show that the opposite is true.
Increased temperatures and too much CO2 can affect water and mineral availability.
As for any biological system, equilibrium is necessary for health.
The Earth is sensitive to environmental change.
We need to become educated about how the Earth works to balance human activity with the needs of the biosphere.
Global temperatures have increased above average for several decades.
The space is used for storing hydrogen ion (H+).
Two H+ remain in the space after water is oxidized.
The electrons give up energy as they move from carrier to carrier, which is used to pump H+ from the stroma into the thylakoid space.
There are more H+ in the stroma.
