Particularly relevant in light of the recent scientific report.

Interestingly, there aren't that many climate deniers anymore, even in the U.S., a hotbed of denial.

Most of us are either alarmed or concerned about climate change, yet most aren't taking the necessary steps to solve the problem -- the most common reason is that no one asked. This is so fixable, and we even know how.

Interestingly, people already care, they just don't know what to do / feel like they are alone. But the truth is, a record number of us are alarmed about climate change, and more and more are contacting Congress regularly. What's more, is this type of lobbying is starting to pay off. That's why NASA climatologist and climate activist Dr. James Hansen recommends becoming an active volunteer with this group as the most important thing an individual can do on climate change.

Often you will get a conformational change in the receptor upon agonist/antagonist binding. So, the bound compound changes the electron distribution of the receptor just enough that it's more stable in another state. For AMPA receptors, for example, they're composed of 4 proteins that form, like, columns through a cell membrane. When it's not activated, the 4 proteins are slightly twisted, such that there is no opening between them. With each glutamate that binds, the proteins that make up the AMPA receptor twist slightly, exposing an opening down the middle. The more open the receptor, the more ions can flow through the channel. When an antagonist binds, the quaternary structure of the AMPA receptor is more stable in a deactivated state, even if more glutamate bind. These bindings are typically transitory, so the molecule will kind of "flicker" on and off the receptor, but when concentrations are high, it's more likely to be bound, and when concentrations are low, it's less likely to be bound.

TL;DR: It's about electron charge distributions.

Preventing unwanted pregnancies is a cost-effective and ethical way to reduce environmental destruction and minimize population growth, and 45% of pregnancies in the U.S. are unintended. Of those, 58% will result in birth. Comprehensive sex education would go a long way, too, and many states do not include it in their curricula, even though comprehensive sex education has strong bipartisan support among likely American voters. Many women at high risk of unintended pregnancy are unaware of long-acting reversible contraceptive options, and many men don't know how to use a condom properly, which does actually make a huge difference. Besides that, it could help to ensure everyone has access to effective contraception, so consider advocating policies that improve accessibility of long-acting reversible contraceptives and help get the word out that it is ethical to give young, single, childless women surgical sterilization if that is what they want.

As for the rest of the world, it would help to donate to girls' education. It might also (perhaps counter-intuitively) help to improve childhood mortality by, say, donating to the Against Malaria Foundation.

All that said, population is not the most significant cause of climate change -- it's the market failure. That's why the single most impactful climate mitigation policy is a price on carbon, and the most impact you as an individual can have is to volunteer to create the political will to get it passed.

And returning the revenue from a carbon tax as an equitable dividend would help a little bit with inequality, while creating jobs and growing the economy.

Taxing carbon is in each nation's own best interest, and the IPCC makes clear carbon pricing is necessary.

Policy changes absolutely dwarf the magnitude of the impact of having one less child.

I don't personally think it's helpful or appropriate to try to discourage people from having children they want. From a population perspective, it makes much more sense to focus on preventing unwanted pregnancies, because there are an awful lot of those, especially in the U.S., where our individual footprints are especially high.
