The voracious appetites of pests put plants under constant stress. They have to fight just to stay alive. And fight they do. Far from being passive victims, plants have evolved potent defenses: chemical compounds that serve as toxins, signal an escalating attack, and solicit help from unlikely allies.

In some cases plants lure attackers into a carefully set trap. An example: plants in the Brassicaceae family (including broccoli, cabbage and mustard) store seemingly harmless compounds known as glucosinates in cellular compartments next to stores of enzymes called myrosinase. The two reserves are separated only by a thin cell wall. When an unsuspecting herbivore chews through this wall, the myrosinase enzymes mix with the glucosinates, catalyzing chemical reactions that engulf the attacker in a toxic cloud. It’s these reactions that give Brassicaceae species their characteristic bitter flavor and antioxidant properties.
Wind power environmental impacts include land use issues and challenges to wildlife and habitat.
The environmental impacts associated with solar power can include land use and habitat loss, water use, and the use of hazardous materials in manufacturing.

A recent study finds 2,206 onshore wind, hydropower, and solar PV energy generation facilities have ‘already encroached on many of the word’s most important places for conserving biodiversity’, degrading 896 protected areas, 749 key biodiversity areas, and 40 distinct wilderness areas.

Even more concerning, the number of active renewable energy facilities inside important conservation areas is poised to increase by about 42% by 2028. To avert climate change, the United Nations demands a 10-fold increase in renewable energy by 2060. This emphasis will especially occur in developing regions like Southeast Asia and sub-Saharan Africa, where the most biodiverse regions in the world are most threatened.
Historically, climate activists like to use ‘climate change’ as an immediate go-to cause for anything they can’t explain or ignore data that don’t fit their apocalyptic claims.
From ‘where the rubber meets the road’ department, comes the bombshell finding that flies in the face of claims about the universal boogeyman of ‘climate change’ killing salmon due to its supposedly water temperature in streams where they spawn. Last year, PBS and Popular Science were screaming about ‘climate change’ being the cause.Â

Kerry recently commented on Covid-19: âIt’s a tragically teachable moment. I don’t say this in a partisan way. But the parallels between COVID-19 and climate change are screaming at us, both positive and negative. You could just as easily replace the words climate change with COVID-19; it is truly the tale of two pandemics deferred, denied, and distorted, one with catastrophic consequences, the other with even greater risk if we don’t reverse course. The long-term parallels between this pandemic and tomorrow’s gathering storm of climate crisis are more clear. If the economic devastation of the coronavirus pandemic is costly today, the cost of climate inaction will matchâif not exceed our current expenditures, which is why the next administration must act with urgency on day one.â
