The investment community has begun to respond, if not in practise than at least in words, to Ross's declaration that 2019 is "the year the world woke up to climate change." Concerns regarding environmental, social, and governance (also known as ESG) are increasingly widely recognised as having an effect on the decisions made in the capital market. ESG considerations are now routinely incorporated into investment analyses conducted by fund managers and private wealth managers, investment banks, pension plans, and individual investors. Additionally, businesses regularly publicise their ESG credentials. By the year 2020, "68 percent of UK savers wanted their investments to evaluate the impact on people and planet alongside the financial performance," as stated by Ross.

More than just a Glance at the Whole

The book "Investing to Save the Planet" is geared toward private investors as its target demographic. It does an excellent job of accomplishing its aim, which is to present a condensed, clear introduction to environmentally responsible investing while omitting no essential material.

The chapters go quickly and combine an incredible amount of information with the author's personal anecdotes and experiences. This is not merely something that will make you feel wonderful. It is likely that readers who are interested in this book value ESG for deeply personal reasons, and the personal narratives that are covered in this book put the quantitative facts in a context that is rich and complicated.

At the end of each chapter is a practical piece of advice labeled "What Should I Do?" As a way to demonstrate that Ross has a deep understanding of the needs of her audience, she presents different lists of proposed actions for low-, medium-, and high-risk investors.if you want to get more information

Hi. You know that, for example, using red and green light together doesn't really make yellow light? It's an illusion caused by the human vision system. We have receptors, nominally red, that is sensitive to red but also a fair way into yellow. Nominally-green responds to orange through to cyan. Etc.

So true spectral yellow of 580nm excites the red and green cones. Your brain is wired to know that, so something stimulating R + G is assumed to be yellow. But it could also just be a red and green light, separately, shining on the same area, reflecting into the eye. Seeing red and green simultaneously, the brain assumes it's seeing yellow, but no 580nm is there, just 550nm and 650nm. The brain can't comprehend two separate colours in one area. So it assumes.

Of course, that's how your monitor works. But at school it was implied the colours "mix" somehow or somewhere, perhaps on the illuminated object. But we're also taught that light waves of different colours don't interfere. The final step, it's an illusion in the human head-meat, I was certainly never told and I don't think most people are.

If a plant cares about colour (and they do), then you have no yellow to offer them. The chemical reactions in their leaves aren't fooled by imitation yellow! (or magenta, or any other visible colour beside the 3 you have supplied).

So my point is, perhaps you need a wide spectrum of LEDs, you can get them in all sorts of in-between wavelengths, it's surprising how many variants there are, even plain red and green have a few varieties, often "superbright" LEDs are just of a wavelength we respond better to.

I'm not certain whether you need these other wavelengths, just pointing out something that, certainly, I wasn't aware of for quite a long time into my adult life. 

Oh of course this R+G+B illusion thing also applies to most cameras! They use the same system, since they were built for humans. This might not be a problem, since like us, they can see yellow, even though they really can't see yelllow! So you can still take photos of whichever wavelength, you just need to be sure you're applying the correct one.

[hmm, wouldn't it be interesting to make a camera whose RGB filters were very strict and narrow? so they'd only detect a narrow band around 650nm red, etc. Yellow or cyan would show up dark, not pass the receptor. In a way it would demonstrate human sight and how things actually look! In a way...]
