Overpopulation & Overconsumption.
Plastic Production.
Emission of Carbon Dioxide and Other Greenhouse Gases.
Destruction of the Reefs.
Production of Black Carbon.
Draining Streams/Rivers and Destruction of Critical Freshwater Aquifer Recharge Areas (Water Pollution)

The tightness with which a chemical attaches to a binding site is termed its affinity for that site, while the effectiveness of the binding chemical is termed its efficacy.
Affinity quantifies how well a medication binds to a receptor (or how well it "fits the lock").
The ability of a drug-bound receptor to induce a response (or "turn the key") is referred to as efficacy.
While antagonists only have affinity for the receptors and no (zero) effectiveness, agonists have both affinities and efficacy for the receptor.
Effectiveness governs what transpires after the medication has been attached to the receptor through affinity.
The affinity (potency) and/or efficacy of different medicines that bind to the same receptor and elicit the same type of response will often vary from one another.

The alveolus (singular form) or alveoli (plural
form) are tiny sacs of organs that are attached to the ends of the alveolar
duct. These tiny sacs of air are clumped together that form interconnected
caves, working together as a unit. They are found inside the lungs and they
make the exchange of air easy and possible. Alveoli units are responsible for
putting oxygen into the air that we breathe in. Blood that passes through the
heart and into the lungs are converted into oxygen which will be then
transported by the blood all over the body systems.
<span>
The walls of the alveoli are extremely thin to
enable the quick exchange of gases Aside from this, the linings of alveoli
units are fluid in nature enabling gases to dissolve. </span>
