#airquality

Clean air is the most important thing for life on Earth 🌎. Humans, animals, and plants all depend on it to stay alive and healthy. Without clean air, it becomes difficult to breathe and living things cannot live long ⛔.

For humans, the oxygen in the air is essential. Every cell in our body needs oxygen to produce energy 💪. Breathing polluted air can cause asthma, lung disease, heart disease, and other health problems 😷. Clean air helps people live longer and stay active.

Animals also need the oxygen in clean air to breathe. Birds, mammals, insects, and aquatic animals all depend on oxygen to survive 🐦🐘🐠. Polluted air can damage their lungs, affect growth, and even reduce their chances of survival. Many animals are sensitive to smoke, fumes, and chemical gases, which can damage entire ecosystems 🌳.

Plants also need clean air. They absorb carbon dioxide (CO₂) from the air for photosynthesis, the process by which food is made 🌱☀️. This process also releases oxygen, which humans and animals need. Air pollution can block sunlight, damage leaves, and slow plant growth 🌫️. Without plants, the balance of oxygen and carbon dioxide in the air can be disrupted, affecting all life.

Vehicles 🚗, factories 🏭, burning waste 🔥, and many other human activities cause air pollution. Protecting the air means planting more trees 🌳, reducing emissions, using clean energy ⚡, and avoiding burning waste.

I support the new clean auto rules! And I oppose defunding climate policies!

316 so far! Help us get to 500 signers!

I am thrilled that the U.S. finalized strong climate change rule for cars yesterday. These rules will force automakers to ramp up electric vehicle sales and slash emissions from gas-powered models. The rule also would reduce fine particulate matter — the most risky form of pollution to our health. Only seven countries met global guidelines for it last year. The fact that the U.S. is leading the world on climate action is great news!

I know that fossil fuel companies are likely to challenge this rule. I want you to stand with the Biden administration and fight back. We are in a climate emergency and we are losing. We need to do much, much more to avoid the worst consequences of a warming planet. This strong rule is a needed next step. I expect Congress to back it and do even more.

As for the Republicans’ trying to defund President Biden’s green tax credits? Absolutely unacceptable. I consider it an outrage that GOP lawmakers are putting oil and gas companies’ profits above our children’s futures. They need to stop right now. Thanks.

PCB of the day! SGP40 Air Quality Sensor Breakout - VOC Index - STEMMA QT / Qwiic 👃🥛🌬️

sniff sniff … do you smell that? You no longer need to stick your nose into a carton of milk; you can build a digital nose with the SGP40 Multi-Pixel Gas Sensor, a fully integrated MOX gas sensor. This is an excellent air quality sensor from the sensor experts at Sensirion, with I2C interfacing, so you don't have to manage the heater and analog reading of a MOX sensor. It combines multiple metal-oxide sensing and heating elements on one chip to provide more detailed air quality signals.
