People began using cotton in prehistoric times as early as 6000–7000 BCE .

Cotton is primarily used for clothing (jeans, t-shirts, underwear), home textiles (sheets, towels, curtains), and industrial products like tents and fishnets.

Like many natural materials, such as comfort and breathability, long-lasting durability.

2. People have used natural rubber for at least 3,500 years

3. Manufacturing vehicle tires (over 50% of production), footwear soles, hoses, belts, and medical supplies like gloves

4. excellent tensile strength, and superior damping properties

2. People start using it in the 1600BC. But first Columbus saw it, when he discovered America.

3. They used for example balls for the little ones and there was a ball game in Mesoamerica called Ritual ball. They also used for waterproofing their clothes and houses.

4. Rubber has so much advantages like, it's elasticity, airtight, and waterproof.

But it also have so much disadvantages like, some people allergic to it, and it has environmental degradation, and also temperatrure sensitivy.

Natural rubber comes primarily from the milky white sap (latex) of the Hevea brasiliensis tree,

People have used natural rubber for thousands of years, with the earliest evidence dating back to approximately 1600 BC in Mesoamerica.

Rubber is a highly versatile material used primarily for its durability, flexibility, and elasticity, with over half of all production dedicated to automotive tires. Beyond transportation, it is essential for manufacturing seals, gaskets, hoses, and conveyor belts in industrial applications.

Rubber offers high elasticity, excellent tensile strength, and superior damping properties, making it ideal for tires, seals, and shock absorption. While natural rubber provides excellent tear resistance, it degrades under UV light, heat, and chemicals.

People start using rubber early as 1600 BC.

The rubber used for a vast range of products due to its elasticity, durability, and waterproof properties, with over half of all production going toward tires for vehicles.

Rubber prized for its high elasticity,, excellent durability, abrasion resistance, and vibration dampening,

Where does it come from^_:

Natural rubber comes primarily from the milky white sap (latex) of the Hevea brasiliensis tree

When did people start using it:

People have been using natural rubber for thousands of years, with the earliest known use dating back to approximately 1600 BC

What do they use it for:

Rubber is a waterproof, and elastic material used in over 40,000 products, most notably for vehicle tires, which consume roughly half of all production. Key uses include automotive parts (hoses, seals, gaskets), footwear, medical gloves, household items (bands, mats), sportswear, and industrial machinery components. 

What advantages and disadvantages does it have^:

Rubber is a very useful material found in many things, from car tires to shoes. It has special qualities that make it hard to replace, but it also has limits. 

when did people start using it? at least 3,500 yearsindustrial seals, gaskets, hoses, conveyor belts, footwear, medical gloves, mats, flooring, and consumer products like rubber bands and elastic clothing. 

What advantages and disadvantages does it have ? Key advantages include superior flexibility, shock absorption, electrical insulation, and, in some cases, high tear resistance. However, it is generally sensitive to oil/petrochemical degradation, suffers from ozone/UV aging, and is difficult to recycle. 

1: Cotton is a natural, fluffy fiber that grows around the seeds of the cotton plant, which belongs to the genus Gossypium in the mallow family. It is cultivated as a shrub in tropical and subtropical regions worldwide, including the US, China, India, and Uzbekistan. The fiber grows in protective cases called "bolls," which split open when ripe. 

2: Cotton is a natural fiber derived from the seedpods of the cotton plant , which is a shrub related to the hibiscus family. These plants grow in warm, tropical, and subtropical regions worldwide, including the U.S., China, India, and Uzbekistan. The fluffy fiber is harvested from the plant, separated from seeds, spun into yarn, and woven into fabric.

3: Cotton is a highly versatile natural fiber used primarily for clothing (jeans, t-shirts, underwear), home furnishings (sheets, towels, curtains), and industrial products like tents and coffee filters. Its strength and absorbency make it ideal for textiles, while byproducts like cottonseed oil are used in food and cosmetics.  

4: Cotton is a highly popular natural, breathable, and hypoallergenic fiber, offering superior comfort and moisture control for clothing and bedding. Key benefits include softness, easy care, and durability. However, cotton has disadvantages, including a high tendency to wrinkle and shrink, a slow drying time, high environmental impact due to water/pesticide usage, and, in some cases, a high cost.

While aluminium compounds (alum) were used as early as 5000 BCE

Aluminum is a lightweight, corrosion-resistant, and durable metal extensively used in transportation (aircraft, cars), construction (window frames, siding), packaging (cans, foil), and electronics (laptop casings, heat sinks

Aluminum is a lightweight, corrosion-resistant, and highly malleable metal with excellent thermal conductivity and, crucially, it is 100% recyclable.

Natural rubber comes from the milky white sap, or latex, of the Hevea brasiliensis tree

The first to use natural rubber, dating back to approximately 1400BC to 1600BC

• 1600 BCE - 400 BCE: The Olmecs (whose name translates to "rubber people") used latex for balls, footwear, and containers.

  
  

is prized for its high elasticity,, excellent wear resistance, and, tensile strength, making it ideal for tires, seals, and shock absorbers.

2 People started using rubber in 1600 BC.

3 Rubber is elastic, durable and waterproof, so it is used for making tires for vehicles.

4 Adantages: very elastic, durable, it can't fray easily, so if the car goes into a hole it can't damage the tire. Disadvantages: it can get a hole in easily, it is durable and non- biodegradable.
