Pollution isn’t just “bad for the environment.” It damages human health, contaminates food and air, and pushes long-term costs onto future generations who didn’t choose any of it.

These effects compound over time like healthcare costs rise, ecosystems lose resilience, and once certain thresholds are crossed, the damage becomes irreversible or wildly expensive to fix. Allowing pollution is essentially choosing short-term convenience while guaranteeing long-term instability.

Over time, those costs show up as chronic disease, resource shortages, and degraded living conditions. By the time the consequences are obvious, the people responsible are often gone, leaving others to deal with the fallout.

Even though bacteria reproduce asexually, they don’t remain unchanged across generations. In the original population, some bacteria likely had small random mutations that made them slightly more heat-tolerant, even if the trait wasn’t obvious at first. When exposed to heat, most bacteria died, but these few survived.

Since bacteria reproduce by cloning, the survivors passed this heat-tolerant trait to their offspring. By the seventh generation, most of the population descended from these survivors, making heat tolerance appear like a new trait. In reality, it’s the result of natural selection acting on random mutations, not learning or intentional adaptation.

At HRC Club, the focus is mostly on high-performance RC cars rather than entry-level or toy stuff. The crowd there really leans toward petrol-powered RC cars—they’ve got strong engines, proper speed and torque, and give that raw, real racing feel that serious RC enthusiasts look for. These cars are built tough too, so they hold up well whether you’re just running laps for fun or actually racing.

Alongside the petrol models, HRC Club also has electric RC cars that are more beginner-friendly. They’re quieter, easier to maintain, and a good option for people who want performance without dealing with fuel, tuning, and constant mechanical work.

A crescograph is a device used to measure plant growth, especially the tiny, almost unnoticeable movements plants make while growing. It was invented by Jagadish Chandra Bose, and honestly, it doesn’t get enough credit outside textbooks.

The whole point of the instrument was to prove that plants aren’t passive or “dead”—they react to light, heat, chemicals, and touch in measurable ways. The crescograph magnifies these minute growth changes so they can be observed and recorded, which was a big deal at the time and changed how people thought about plant physiology.

In short, it’s less about measuring height and more about proving that plants are actively responding to their environment.
